should `guix deploy` work with dropbear?

on one of my servers i have replaced openssh with dropbear.

(service dropbear-service-type
         (dropbear-configuration
          (port-number 22)
          (password-authentication? #false)
          ;; To allow `guix deploy` to connect as root.
          (root-login? #true)))

i `guix deploy`ed the config, even rebooted the machine. all works fine, except when i want to `guix deploy` once again:

$ guix deploy x.scm
The following 1 machine will be deployed:
  lendvai

guix deploy: deploying to lendvai...

the ssh login part seems to have worked fine according to /var/log/secure:

Sep 16 23:10:53 localhost dropbear[489]: Exit (root) from <...>: Exited normally
